I was unsuccessful in an internal application with my company. I usually send a thank you note to the hiring manager and other interviewers afterwards but i've never been rejected for an internal move before where the hiring manager/interviewers are coworkers.
Is it still appropriate to email a thank you note to them if the role was internal?
Edit: Follow-up - is it inappropriate to ask for feedback if it was an internal role? I feel like it would be more awkward to fob me off, if so ill not ask.
